To reproduce the problem, use the setQuoteIdentifer example from Aqua OpenAPI > IO > AquaScripts > AQTextProcessor > setQuoteIdentifier.xjs

The second part of the example script calls reader.setQuoteIdentifier(2, "\'");

Actual results from the example:

Set input string ["Column A"|"Column B"|'Column C']
Set QuoteIdentifier for all columns to """
Set field delimiter to [|]
  0: Column A, Column B, 'Column C'



Set input string ["Column A"|"Column B"|'Column C']
Set field delimiter to [|]
Set QuoteIdenitifer for column 2 to "'"
Read input string with delimter set:
  0: "Column A", "Column B", 'Column

The highlighted output is incorrect.  Expected output is:

  0: "Column A", "Column B", Column C
